We have 2 main exchange servers, one with a 14gig is store, and the other is
at about 4gig... and growing...
And another exchange server acting as an IMC (no mailboxes)
We run all exchange backups at midnight every night (all at the same time to
a disk pool)
We are using the same network that everything else uses... but I trying to
test a backend network solution and see if I can push the speed up some...

Here's a snippet of the output of my cmd file that runs every night...
